Description

Technical Field

[0001] This utility model relates to the technical field of liquid separation equipment in hydrometallurgy, and in particular to a filter head for extracting supernatant. Background Technology

[0002] In hydrometallurgical production, materials typically require multiple boiling and washing separation operations after reaction to remove impurities and improve purity. However, when the amount of material to be processed is small, continuous operation in multiple tanks is not only costly in terms of equipment investment but also cumbersome and energy-intensive, failing to meet the economic requirements of actual production. Therefore, in actual production, multiple boiling and washing separation operations are often completed in a single tank. The specific operation process is as follows: wash water is continuously added to the tank to boil and wash the material; after boiling and washing, the supernatant in the tank is extracted to separate the solid material from the liquid supernatant. Currently, the supernatant is extracted using negative pressure extraction, which involves connecting a suction device via a negative pressure pipe. However, the existing extraction device lacks an effective filtration structure. Under negative pressure, some fine material particles are drawn away along with the supernatant, resulting in a reduced material yield. Furthermore, during operation, operators cannot precisely control the depth of the negative pressure pipe inserted into the tank. If the pipe is inserted too deeply, it will directly contact the material layer at the bottom of the tank, causing the material to be sucked away. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a filter head for extracting supernatant, which solves the problems of low separation efficiency and poor operational controllability in the extraction of supernatant in the hydrometallurgical industry in the prior art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A filter head for extracting supernatant includes a cylinder with a plurality of filtrate holes evenly distributed on the side wall of the cylinder. A filter cloth is provided on the side wall of the cylinder and is attached to the side wall of the cylinder. The mesh size of the filter cloth is smaller than the mesh size of the material particles. One end of the cylinder is connected to a suction pump, and the other end is connected to a telescopic sleeve.

[0005] Threaded sleeves are fitted at both ends of the cylinder.

[0006] The telescopic sleeve is a multi-section telescopic structure.

[0007] The length of the cylinder is 10-15cm.

[0008] The outer wall of the telescopic sleeve is provided with an anti-corrosion layer.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting filter cloth on the side wall of the cylinder, and the mesh size of the filter cloth is smaller than that of the material particles, it can ensure the smooth passage of the supernatant while preventing the solid material from being drawn away by the negative pressure, thus significantly improving the material yield. It is especially suitable for the separation of valuable materials such as gold powder. The setting of the telescopic sleeve allows the operator to flexibly adjust the overall length of the filter head according to the depth of the material layer in the tank, avoiding the filter head from being inserted too deeply into the material layer or the extraction efficiency being reduced due to insufficient length. This solves the problem of the difficulty in controlling the insertion depth of the traditional negative pressure pipe. The cylinder length is set to 10-15cm, and multiple filtration holes are evenly distributed on the side wall, increasing the inlet area of ​​the supernatant. Combined with the negative pressure of the suction pump, the supernatant can be quickly extracted. The anti-corrosion layer on the outer wall of the telescopic sleeve can resist corrosion from acidic and alkaline liquids, preventing the telescopic sleeve from being damaged by corrosion, extending the overall service life of the filter head, and reducing the equipment replacement cost for enterprises.

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0013] A filter head for extracting supernatant includes a cylindrical body 1. A plurality of filter holes 2 are evenly distributed on the side wall of the cylindrical body 1. The filter holes 2 penetrate the side wall of the cylindrical body 1 to allow the supernatant to enter the interior of the cylindrical body 1. A filter cloth 3 is provided on the side wall of the cylindrical body 1. The filter cloth 3 is attached to the side wall of the cylindrical body 1. The mesh size of the filter cloth 3 is smaller than the mesh size of the material particles to ensure that the supernatant can pass smoothly through the filter cloth 3 and enter the filter holes 2, while preventing solid material particles from passing through the filter cloth 3. One end of the cylindrical body 1 is sealed and connected to the suction end of an external suction pump for extracting the supernatant inside the cylindrical body 1 by the suction pump. The other end is sealed and connected to one end of a telescopic sleeve 4. Threaded sleeves 5 are fitted at both ends of the cylinder 1. The threaded sleeve 5 at one end of the cylinder 1 is threadedly and sealed to the suction end of the external suction pump, and a sealing gasket is wrapped around the connection. The telescopic sleeve 4 is a multi-section telescopic structure. The telescopic sleeve 4 is used to adjust the overall length of the filter head to adapt to the depth of the material layer in different tanks and to avoid the end of the filter head from contacting the material layer. The length of cylinder 1 is 10-15cm. When the negative pressure is large, the length of cylinder 1 can be increased. When the negative pressure is small, the length of cylinder 1 should be shortened. The longest length should not exceed 15cm. If it is too long, the supernatant cannot be completely drained. The shortest length should not be less than 10cm. Otherwise, the extraction effect will be poor. Only after a small amount of air is introduced can the supernatant be extracted better. The outer wall of the telescopic sleeve 4 is provided with an anti-corrosion layer. When using: Adjust the length of the telescopic sleeve 4 according to the depth of the material layer inside the tank. When the cylinder 1 is partially inserted into the supernatant, the end of the telescopic sleeve 4 does not contact the material layer at the bottom of the tank. Start the suction pump, and under negative pressure, the supernatant passes through the filter cloth 3 and the filtrate holes 2 on the side wall of the cylinder 1 in sequence and enters the interior of the cylinder 1. Then, the supernatant is extracted by the suction pump. During this process, the filter cloth 3 prevents gold powder particles from passing through, thus preventing gold powder from being drawn away with the supernatant. This utility model has a small number of overall structural parts, low manufacturing cost, and is easy to install and disassemble, facilitating daily cleaning and maintenance. It is suitable for the separation of tanks of different specifications and various hydrometallurgical materials. The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
